MALeoLM s. sInPlsoN, or PITTSBURGH, PENNSYLVANIA, AssIGNoR To PREssRD STEEL CAR COMPANY, or vrrrussRURen,` PENNSYLVANIA, a CORPORATION or NRW JERSEY.

Vin the county of Allegheny Be it known that I, MALCOLM S. l a citizen ofv the United State"s,'residing at Pittsburgh Athletic Association, Pittsburgh, and State of Pennsylvania, have invented certain new l and useful Improvements in Mine-Cars. of

which the following is a specification.

An object of the invention is to provide "'asimple, light and strong underfrarne ond construction for mine or like cars which will withstand withoutsubstantial damage the heavy shocks and jars to which acar o this type is subjected, and also protect from damage the remainder of the underframe and the car body..

Another object of the invention is to provide an efficient bumper for mine cars which .if damaged may be easily and quickly removed or replaced.-

A further objectof the invention is to provide novel means for removably securing a bumper to a mine or like car.

With the above and other objects in view the invention resides in the construction, arrangements and combinations of hereinafter described and claimed.

Referring now to the drawings, in which like reference characters refer to like parts, Figure 1 is a planview of a portion of a car constructed in accordance with the invention; Figs. 2 and 3 are side and end ele vational views respectively of the same;

las

. be of any suitable form, drawings are preferably Fig. 4 is a cross sectional view taken on the line 4 4 of Fig. 1; Fig. 5 is a longitudinal sectional view taken on the line 5-5 of Fig. 1; and Figs. 6 and 7 are end and. side elevationalpviews respectively of a. car embodying a modification of the invention.

Referring now in detailto the drawings, l, l indicates spaced sill members which may but as shown in the of channel form in cross section. These sill' members preferably terminate short of the ends of thecar body, but it will be understood that they may extend fon'ithe full length of said body.

2 indicates avmember which extends between the sills-'1,"1 ina direction transversely of the car and at its ends is provided with flanges 3, 3 which are secured to the webs of such sills. This member 2 may be of any suitable form, but is preferably of `Z formy incross section,

flanges 5 l and 6 respectively, disposed horizontally 1n opposite directions,the 'flange 5 transverse centerline of the car and the flange 6 being disposed in a direction toward the end of the car. Seated on and secured to the flange 6 of the transverse member 2, are members 7, 7, which extend outwardly to the end of the car. These members are section having their webs 8, 8 disposed vertlcallyrand their top and bottom flanges 9 and lf) respectivelypdisposed horizontally in opposite directions, the flange 9 of each member being disposed in a direction toward the side of the car and the flange 10 being disposed in a longitudinal centerline of the car.

11 indicates the floor which preferably comprises a flat plate which extends from end to end of the car body and is preferably secured to the upper flanges 12 of the sills 1, l, the upper flange 5 of the member 2, and the upper flanges 9 of the members 7, 7, thusassisting in rigidly' connecting all of said members.

13 indicates a buffer beam which is pref` erably of wood and which preferably comprises a plurality of sections, which are sup- `ported at their inner ends bythe flange 6 2 and may be secured to such flange by bolts 14, or other vsuitable means. This buffer beam extends outwardl from themember 2 to a point beyond t e end of the car body and at its guard or buffer plate 15 which'is of U or section. This beam is supported, longitudiatits side portions, by the flanges 10 of the members 7, 7. To prevent the spreading of the members 7, 7 when the car receives a heavy end shock and to furof the buffer beam, bolts 16 are provided which extend vtransversely of the car and pass through the webs 8 of the members 7, 7.

At or near'the end of the car body a transverse member 17 is Vprovided which, as

shown in Figs. 1, 2 and 3 of the drawings,

is preferably of channel form in cross section, but as shown in Figs. 6 and 7 of the drawings, this member may be in the form of a flat plate. This member is provided portions 18, 18 which are preferably secured to the side walls 19, 19

preferably of Z form in cross other suitable being disposed in a direction toward the direction toward the Asa..

' lof the car body,`and is also provided with ings, the end wall of the car body may comrise a door 23, or as shown in Figs. 6 and may comprise an end plate 24: which may be connected with the side walls 19. It will be understood that .the construction of the underframe may be identical at both ends of thecar, or if desired the underframe at one end of the car may be `-constructed in accordance with Figs. 1, 2 and 3 of the drawings, and at the other end constructed in accordance with Figs. 6 and 7 of the drawings.

I do not wishrto be limited to the exact construction of the end framing body and bumpers as described in the specification,

for it will be apparent to those skilled in the art to which this invention appertains, that many changes may be made without .departing from the spirit and scope of the inven-V tion as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is:

1. In a m ine,car,'spaced sill members, a transverse member between and secured to said sill members, longitudinal members extending outwardly from said transverse member tothe end of the car and a buffer beam carried by said transverse and longitudinal members.

2. In a mine car,lspaced sills, atransverse member extending between and secured to said sills, side walls, la transverse member secured to said side walls, and a bufl'er carriedby said transverse members. 3. In a mine car, spaced sills, a Z shape member extending between and secured to said sills, a buffer beam resting on saidl member, and means for removably securing said beam to said member.

4. In a mme car, spaced sills. ,a Z shaped member secured between said sills, Z shaped members secured to sa1d member, and a' buffer beam removably carried by said Z shaped members.

5.

8. In a mine car, a transverse underframe member, a plurality of spaced longitudinal members secured to said transverse member, a floor secured to said transverse and longitudinal members, a transverse member at the end of the car, and gusset members interposed between and secured to said longitudinal members, floorand last mentioned transverse member.

9. In a mine car, spaced sills, a transverse member secured between saidv sills, spaced longitudinal members secured to 'said transverse member'and extending to the end of the car, and a buffer beamV carried by and lllling the space between said transverse and longitudinal members.

10. In-a" mine car, spacedsills, a transverse member secured between: said sills, spaced longitudinal members secured to said transverse member and extending to the end of the car, and a buiier beam carried by and filling the space between said transverse and versely extending member-"secured between said sills, spaced longitudinal members secured to saidtransverse membenfsaid mem-v bers having upper and lowerfflanges, a floor secured to said upper flanges fand a buffer beam carried by said lowerflanges.

13. In a mine car, spaced sills, a transversely extending member'secured between' saidl sills, spaced longitudinal members secured to said transversefme'mber, said members having upper andflower flanges, va floor secure-d to said upper flanges and fay buffer beam carried by said lower flanges, said buffer beam lilling the space betweensaid members and between said floor and lower flanges. f f i M 14. In a mine car, a pluralityof spaced transverse flanged underframe members, spaced longitudinal flanged members se'- cured to said transverse members, and a` buffer beam carried by said flanges.

15. In a mine car, spaced sills, a transand all of said members, side walls secured 15 verse member secured to said sills, spaced longitudinal members secured to said transverse member, said longitudinal and transverse members having upper and lower flanges, a floor plate secured to the upper flanges of said members and a buffer beam" carried by said lower anges beneath said floor.

16. In a minecar, spaced sills, a transverse member secured between said sills, spaced longitudinal members having their inner end portions secured to said transverse member, a Hoor plate secured to said sills to said sills and floor plate, a transverse member connected with said side walls adapted to extend below and support the outer end portions of said longitudinal members, and a buffer beam removably secured between said longitudinal members.

In testimony whereof I aix my signature in presence of two witnesses.
